Is any chip exsisted which has TCP/IP hardware and software implemented inside the chip so that to use the TCP/IP communication can be done easily? I am not familair with the TCP/IP and want to find quick way to implement our system with TCP/IP connection. Also, the develop tools is better C(although a few assembly is OK).

When I upload data from DPS (where my tcp implementation is) to windows (an ftp server takes the data there), the windows tcp hangs at times. It happens only at 100 MbpS. Something like 8 megabytes/S get sustained for a few seconds with several retries, then at some point the windows tcp acks only part of the last segment it could take with a window size of 0. My tcp retransmits that seg...

There are many freely available TCP/IP stakcs (OpenTCP, lwIP, ethernut etc.) as well as many commercial ones (NetX, CMX, ...) . I would appreciate if you can comment on the performance of TCP connections (as well as UDP, if available). The type of micro used as well as CPU clock is also usefull. This is not a school project nor market survey. I simply want to see what can I expect from...

I'm looking to streamline a tcp stack for use on the Renesas H8 series microprocessors. I would like to solicate your opinions on a few stack optimizations I have in mind, what others might be possible, and the performance which might be achieved. For my application only tcp input is required. This should eliminate the need to maintain timers and thus allow for a purely interrupt driven ...

Hi, I am just gathering informations on how to equip an existing device with an ethernet interface in order to enable remote tcp/ip access. Most of the available tcp/ip stacks as well as chips with built-in tcp/ip functionality I found so far only support ipv4. My question is: isn't this a dead end? Don't I have to expect the demand to upgrade to ipv6 quite soon? I know ipv6 puts a lot ...
